RFQ checklist
询价清单：型号或阀门类型、DN/NPS、PN/Class、整定压力、泄放介质、工作温度、阀体及内件材质、进出口连接标准、阀帽/杠杆/先导选项、数量、图纸、证书及检验要求。.
Failure Analysis, Manufacturing Evidence and Quality Control
Common misapplication risks: incorrect thread or connection standard, insufficient certified relieving capacity, unsuitable body or trim material, operating pressure too close to set pressure, unreviewed back pressure, and installation loads transferred to the valve.
Material review: body materials: WCB, CF8, CF8M and CF3M body material options. Trim and internals: Stainless and hard alloy trim selected by body material and medium. Spring and stem: 50CrVA spring for standard service; stainless or coated fluoroplastic/304 spring options for corrosive service where specified.
Testing and inspection: Set pressure calibration, shell strength test, seat tightness/leakage test, reseating/blowdown check, dimensional inspection and material verification can be supplied according to the confirmed standard and order requirements.
Source and scope: product data is based on Zobai Safety Valve Product Catalog.pdf, catalog page 049-050. Project compliance remains subject to the approved datasheet, drawing, calculation and controlled certificates for the ordered configuration.
Review material traceability, type-test scope 和 project certificate requirements.
